LATCH WITH PIVOTED CASE.

Application filed January 31, 1908.

T 0 all whom it may conce/ra.'

Be it known that I, LOUIs C. LEOPOLD, a citizen of the United States, residing at Hancock, in the county of Pottawattamie, State of Iowa, have invented certain new and useful Improvements in Latches with Pivoted Cases; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to combined catch and latch, the object of the invention being to provide a construction which may be pivoted upon a door to swing into and out of engagement with a notched keeper, or may be 'fixed upon a door so that the bolt forming `an element of the structure may be slid into or out of engagement with the hooded keeper.

A further object of the invention is to provide a stru cture comprising a minimum number of parts so constructed and arranged as to be least expensive.

In the drawings forming a portion of this specification and in which like numerals of reference indicate similar arts in the several views, Figure 1 is a top p an view of the invention. Fig. 2 is a longitudinal horizontal section through the casing, the bolt being engaged with a hooded keeper. Fig. 3 is an elevation showing the' casing pivoted to a door and raised from engagement with a notched keeper. Fig. 4 is a side elevation of the notched keeper illustrated in Fig. 3, and showing the bolt engaged therewith. Figs. 5 and 6 are sectional views on lines 5 5 and 6-6 respectively of Fig. 2.

Referring now to the drawings, the present invention is illustrated as comprising an integral casing including a vsemicylindrical portion 5 having side ianges 6and 7 at one end and having an end flange S at the opposite end of the casing. The central portion of the casing includes an enlarged chamber 9 which opens through the rear side of the casing and from this enlarged chamber 9, there extend two passages 10 Aand 11 through the ends of the casing. The passage l() is rectangular in cross section while the passage 11 is round in cross section, as illustrated in Figs. 5 and 6 respectively.

In the casing is slidably disposed a bolt including a squared end portion 12 and a cylindrical end portion 13. The squared end portion 12 asses through the passage 10 of the casing that leads to the enlarged chamber 9,

the mutual engagement ol these two squared portions lserving to prevent rotation ol: the bolt in the casing. The free end of this squared end portion of the bolt projects normally lrom the end o'l the casing and is beveled as shown at 14, so that when in use upon the door, the bolt will be pressed rearwardly when 'l'orced against the keeper 15 in connection with which it is employed.

The cylindrical end portion of the bolt passes through tho cylindrical passage 11 Ol the casing and has a sliding bearing therein. Upon that portion ol the cylindrical part of the bolt lying within the enlarged chamber 9, is mounted a helical spring 16, which bears at one end against the squared portion of the bolt and at the opposite end against the op posite end of the enlarged chamber 9. This spring serves to hold the bolt normally and yieldably with the beveled end of the squared portion protruding Afrom the casing.

In the front face of the casing 5, there is formed a slot 17 lwhich leads into the enlarged chamber 9, and through this slot is passed a ro d 18 which is engaged through the bolt and is provided at its end with knos 19. These knobs provide means for moving the bolt longitudinally from engagement with the keeper.

When used as a catch, the casing is secured fixedly to the face of a door 20 by means of screws passed through pcrforations in the flanges 6 and 7 and by means of a third screw 22 passed through a perforation on the flange S. In this connection there is employed a hooded keeper into and out of engagement with which the bolt is adapted to slide, as will bc readily understood.

Referring now to Figs. 3 and 4 of the drawings, when the invention is to be used as a latch, the screws are omitted from the perforations in the Vflanges 6 and 7, so that the entire structure may swing pivotally upon the one screw that is engaged in the perforation in the -flange 8. The casing may be then swung in a vertical plane to carry the end of its bolt into and out of engagement with the notch of a common type of latch keeper 23.

It will be appreciated from the foregoing, that there is provided a structure which may be used in either of two different specific manners, which comprises a minimum num-.

Having thus described the invention, What is claimed is: I

A combined latch and catch eo'nsistingof a casing formed integral, said casing 'having a central enlarged chamber opening through its rear face and having longitudinal passages in its ends opening into said chamber, one of said passages being rectangular in cross seotion and the other of said passages being ey; lindrieaLa perforated ii'ange projecting'longitudinally from one end of the Casing, 'lateral perforated 'flanges projecting from the opposite end lportion of the casing, a bolt passed throughthe easing and having sliding eng-agement'vvith the-passages in the end portion thereof, the-engaging portions lof said bolts being formed to correspond With the cross sections of the assages with Which they are engaged, a he `cal spring mounted upon the cylindrical portion of the bolt and 20 resting With'one end against the rectangular portion of the bolt and With its opposite end against the opposite end of the chamber .of the easing, said easing having a longitudinal slot in its outer face7 and a rod passed 25 through said slot and engaged through the bolt, and having a knob at eaoh end.

In'testilnony whereof, I aHiX my signature, inpresenoe of two Witnesses.
